GAS BURNER.

Application filed July 11,

ordinate with the outlet of explosive mixture v through the mixing chamber or refractory.

A further object of the invention is to provide gas burners whereby the velocity of the gas is not changed when the volume thereof entering the mixing chamber of the burner is reduced, thereby insuring a satisfactory mixture of gas and air before the explosive mixture reaches the point of ignition. and to provide an adjustable outlet to the refractory or mixing chamber whereby a greater range of adjustment can be had.

. Another object is to provide means for adjusting the outflow through the mixing chamber simultaneously with the adjusting of the intake of air and gas.

Another object is to provide control devices by which a uniform flame can be obtained regardless of volume.

This invention is an improvement on the burner shown in the patent granted to me 11,1926,No.1,5s4,546. I

Other objects and advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Y Reference is had to the accompanying drawings which form a part of this application.

inlet chamber 1 and an air receiving. cham- The chamber 2 is also a part of the air and gas mixing cham- Gas is supplied to the chamber 1 through a pipe 3 which is provided with a control valve 4:. A shaft5 is journaled in the bearing 6 which is integral with the casing 1 and also journaled in a bearing 7 which is formed in the partitioned chamber 10. Gas is fed through a perforated disk"8 control valve 9 is revolubly mounted on shaft 5 and bearsagainst the disk 8. The disk 8 is provided with a plurality of perforations 11 and the valve 9 has a plurality of cut-off wings 12. More or less of the perforations 11 can be closed or opened by. turning the shaft 5 which turns the valve 9 and wings-12. A spiral spring 13 is mounted on the shaft 5 and bears against the valve 9 and yielding washer 14. The valve 9 will be turned by the shaft 5 for opening or clos ing the perforations 12. The spring 18 will hold the valve wings 12in'close contact with the disk 8. i

The feeding of the gas will be further controlled by the valve 4. A push rod 15 in two parts is actuated by a handle 16. When the shaft 5 is turned the handle 16 will actuate the push rod 15 to change the amount of gas which will pass through the valve l. The valve 4 co-ordinates with the gas control valve 9 with its wings 12.

The chamber 2 provided with air inlets 17 and an air-control valve 18 is attached to the shaft 5 and revolves with this shaft. The valve 18 is provided with air passages 19 andequal number of cut-offs 20. The valve 18 will be revolved with the shaft 5 for feeding more or less air to the chamber 2. The valve 18 co-ordinates with the gas of the supply of air and gas is accomplished simultaneously. The amounts of gas and air can be changed when necessary. The valve 18 can be set at differontpositions'on the shaft 5 and the disk 8 can be set at different positions relative the valve wings 12.

The explosive mixtureis formed in the chambers 2 and 10. Means are provided for controlling the discharge of explosive mixture through the nozzle 21. A throttle valve 22 is pivotally mounted in the discharge nozzle 21 and may be held yieldingly down by'a spring 23. A rest 24 is provided for the shaft 5 and a cam 25 is rigid with the shaft feed valve 9, thatv is, the increase and decrease will actuate the throttle valve 22.
